Informed consent in medicine is really important. It makes sure that patients understand what is happening with their health care and can make choices about it. This idea comes from different rules and beliefs. Here are the main parts:

• Common Law: This is a set of legal rules that say patients have the right to make decisions about their own health. Doctors also have a responsibility to take care of their patients.

• Statutory Law: These are specific laws that require doctors to follow certain steps for getting consent, especially when it comes to sensitive treatments.

• Case Law: This involves decisions made by courts that help define and change the rules around consent. It shows what society values and thinks is important.

• Ethical Guidelines: Many organizations, like the American Medical Association, set guidelines to support patient rights. They encourage doctors to help patients make informed choices.

Together, these rules and beliefs help ensure that patients are treated with respect and can make educated decisions about their healthcare.
